Zinc　metal　anode,　the　most　promising　candidate　material　for　rechargeable　aqueous　zinc-ion　batteries,　has　attracted　considerable　attention　due　to　its　abundant　resources　and　low　cost.　However,　hydrogen　evolution　reaction　and　uncontrollable　zinc　dendrite　growth　on　zinc　metal　anode　are　the　essential　issues　that　strictly　limit　their　practical　application.　Here,　a　modified　Zn　with　a　titanium　nitride　(TiN)　protective　layer　(TiN@Zn)　using　a　simple　solvent　casting　approach　is　developed,　which　can　simultaneously　suppress　the　hydrogen　evolution　reaction　and　control　the　zinc　dendrite　growth　when　acting　like　a　protective　layer　on　the　Zn　anode.　In　situ　differential　electrochemical　mass　spectrometry　approach　shows　that　the　TiN　coating　layer　can　effectively　suppress　the　hydrogen　evolution.　Additionally,　the　TiN　can　offer　large　Zn　nucleation　sites,　narrowing　the　Zn　nucleation　energy　barrier,　leading　to　a　uniform　Zn　deposition.　Thus,　in　symmetric　cells,　the　TiN@Zn　electrode　presents　a　stable　Zn　plating/striping　(600 h　at　1 mA　cm−2)　and　lower　potential　hysteresis　(38 mV),　resulting　in　an　improved　electrochemical　performance　for　TiN@Zn||MnO2　full　cell.　©　2022　Wiley-VCH　GmbH.
